From 5c33349b3efff36a6acd36c6600b61e7cc2dbffc Mon Sep 17 00:00:00 2001 From: ajs Date: Wed, 23 Feb 2005 15:43:01 +0000 Subject: 2005-02-23 Andrew J. Schorr * ospfd.h: Add new field struct stream *ibuf to struct ospf. * ospfd.c: (ospf_new) Check return code from ospf_sock_init. Allocate ibuf using stream_new(OSPF_MAX_PACKET_SIZE+1). (ospf_finish) Call stream_free(ospf->ibuf. * ospf_packet.c: (ospf_read) Call stream_reset(ospf->ibuf) and then pass it to ospf_recv_packet for use in receiving the packet (instead of allocating a new stream for each packet received). Eliminate all calls to stream_free(ibuf). (ospf_recv_packet) The struct stream *ibuf is now passed in as an argument. No need to use recvfrom to peek at the packet header (to see how big it is), just use ospf->ibuf which is always large enough (this eliminates a system call to recvfrom). Therefore, no need to allocate a stream just for this packet, and no need to free it when done. --- ospfd/ospfd.h | 1 + 1 file changed, 1 insertion(+) (limited to 'ospfd/ospfd.h') diff --git a/ospfd/ospfd.h b/ospfd/ospfd.h index 0f778e0d..2a6c23e9 100644 --- a/ospfd/ospfd.h +++ b/ospfd/ospfd.h @@ -248,6 +248,7 @@ struct ospf struct thread *t_write; struct thread *t_read; int fd; + struct stream *ibuf; struct list *oi_write_q; /* Distribute lists out of other route sources. */ -- cgit v1.2.1
